title: Compact Q-value enhanced bandpass filter based on the EIT-like effect accompanying application in downconversion APL.
abstract: A compact quality factor (Q)-enhanced bandpass filter based on the electromagnetically induced transparency (EIT)-like effect between two-ring resonators was proposed and experimental demonstrated. The enhancement in Q can be 2-3 orders of magnitude compared to the single ring bandpass filter, and a 27 times enhanced bandpass filter with a bandwidth of approximately 4.8 GHz was successfully realized. A downconversion analog photonic link (APL) based on the proposed filter has been presented and the spurious free dynamic range of the link was as high as 103.9 dB-Hz(2/3).
